Dabbling on the topic.

Wondering how many of you guys would be interested in a service where you could walk into your local corner store and buy Bitcoin from the store owner by paying him cash and sell Bitcoin to him to get cash from his cash register?

Let's assume there's a fantastic lightning wallet out there that's super intuitive and easy to use with zero setup time required for new lightning users. Would you use something like this over localbitcoins or a regular centralized exchange? Is cash still a big thing?

Personally, I believe there is no need to use lightning network for this.

You are going to sell a coffee for $1-3, whatever. You can accept zero confirmation payments.
Almost no one will try to double spend the coins, and a 51% attack to rob you $3 is impossible.

Just make a nice sign with Bitcoin Logo (Bitcoin Accepted here) and when someone transfer you and you see the transaction on the blockchain with zero confirmations, that is it. Paid. No worries.
